The Lowdown
Alright, Rusty here. Let’s break down the local outlook for this stretch.
We’ve got a quiet start, but once the swell shows up there are a few days that look real tasty. The real gem here is Karramarro, a point break that loves a good NW swell. It’s an advanced wave and inconsistent—so when it’s good, it’s real good, but don’t expect it to fire all the time.
The first action comes on Sunday, the 30th of August. Morning shows a clean 5ft NW swell with a 10-second interval. The water temp is a balmy 74°, which is well above average for this time of year. Glassy conditions with a light 5 km/h NNE breeze. Wave energy is moderate (415). A solid start.
Monday the 31st of August is even better for the early session. A clean 6ft NW groundswell, same 10-second period, and glassy with just 5 km/h light WNW breeze. The energy kicks up a notch (557). Expect clean lines. Crowds are possible here, so get out there early.
Then things go quiet. From Tuesday the 2nd of September through to the 5th, it’s small and weak—several days of flat or near-flat conditions. A real lull.
Now, the one to get stoked on. Saturday the 5th of September is the standout. The morning brings a solid 7ft NW swell with a very long 14-second period. That’s expert territory at this size. Wave energy is 1688, strong. Winds are glassy from the east at just 5 km/h. For a point break, this long-period groundswell will set up beautifully—long, lined-up waves with plenty of time between sets. It’s quality over quantity that day.
Sunday the 6th of September drops back to a more user-friendly 5ft from the NW, and the afternoon cleans up with a light offshore cross-off breeze. A solid second option.
Bottom line: The best call of the whole forecast is Saturday morning the 5th of September at Karramarro—clean, powerful, and classic point break conditions. Monday the 31st of August morning is your backup if you want something a bit smaller and just as clean.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
